In the layer test, approximately 760 white and brown egg type pullets/strain were placed at the initiation of the rearing portion of the test. However, if the number of hens needed were below the prescribed numbers, they were divided as equally as possible between the levels and replicates within the layer house and placement into the layer test was adjusted appropriately.

Dates of Importance:

The nineteen entries were hatched on January 6, 2010. The chicks were all sexed according to their genetics (vent, feather, or color), vaccinated for Marek’s disease, and wing banded for identification before being transferred to the brood/grow house. Table 1 shows the source of the laying stock, strain which was entered, and participation in the test environments and Table 36 provides the breeder, source of eggs, and entry status of each strain(Cage, Cage Free, or Range Environment). The rearing phase for the range, cage free, and the cage reared pullets complete the grow phase at 16 wks, then transitioned to the laying phase during their 17th wk of age. First cycle production records commenced on May 5, 2010 (17 weeks of age), through the molt period which was induced on May 4, 2011. The molt records commenced on May 4, 2011 (69 weeks of age), and ended on June 1, 2011 (73 weeks of age). The second cycle began on June 1, 2011 (73 weeks of age) and ended on February 15, 2012 (110 weeks of age) This report includes production data summarized from 17 to 69 weeks, 69 to 73 weeks, and 73-110 weeks. A table showing the changes in body weights from 17 to 69 wk of age, weight loss during the molt period, and overall weight gain is included in the information.

Pullet Housing:

The chicks were randomly assigned to the growing cages with white egg and brown egg replicates being intermingled throughout the house. The white egg strains occupied approximately 58 % of the house and brown egg strains occupied the other 42 % of the house. All strains were assigned to be represented as equally as possible in each of room, row, and levels.

The chicks from the brown egg strains destined for the range study were randomly assigned to the growing pens throughout House 2. This work will not be reported further until the single cycle report.

House 8--is an environmental controlled closed brood-grow facility with 3 banks of quad-deck cages in each room. Each room was assigned a number, each side of each bank was assigned a row number, each cage section within each row and level/row has been assigned a replicate number. For statistical analysis, pairs of rows have been designated as blocks. Thus, each block consisted of two rows containing 24 replicates on all levels. This allows for a total of 3,744 pullets per room resulting in a total pullet count for this test in House 8 using 3 rearing rooms of 11,232. The white and brown-egg strains were randomly assigned to the replicates in the house. Entrant strains were assigned to the replicates in a restricted randomized manner with the restrictions being that all strains were approximately equally represented in all rows, levels, and rooms. The chicks were brooded in the same cage during the entire 17 wk rearing period. Paper was placed on the cage floor for the first 7 days within each of the replicate series within each row. Each cage within the replicate was filled with 13 white-egg or brown-egg (13 per 24" x 26" cage) pullets on the day of hatch for a rearing allowance of 48 in2, 4.7 cm (1.8 in) of feeder space/bird and 1:6.5 nipple drinkers to bird ratio. The same numbers of pullets were grown in each replicate for both white and brown-egg strains. The room dividers were removed for this test so that all birds were essentially reared in a contiguous house.

Layer Housing:

The hens were randomly assigned to the replicate cages with white egg and brown egg strains being inter-mingled throughout the houses. The white egg strains occupied 58% of the house and brown egg strains occupied the other 42%. All strains were assigned to be represented as equally as possible in all rows, and levels. Laying Hen Cage Facilities reported in this test consist of two houses. House 4 is a high rise, environmentally controlled facility with three banks of Quad-deck (4-tier) high cages. There are a total of 216 replicates which can support 4,428 hens. House 5 is a standard height totally enclosed force ventilated laying house with a scraper pit manure handling system. It has 2 banks of tri-deck (3 levels) cages and two banks with quad-deck (4 levels) cages. There are a total of 252 replicates in house 5 which can support 5,166 hens.

Cage Layout Description

In both houses, each side of a bank was designated as a row and each row was divided into 9 8-foot replicates/level. The replicates are equipped with feed hoppers to supply and monitor feed consumption for each individual replicate and the feed is distributed by an automatic feeding system. The white-egg and brown-egg strains were assigned to the replicates in a restricted randomized manner, with the restrictions being that all strains were approximately equally represented in all rows, levels and cage sizes.

Test Design:

The arrangement for the laying test involved a completely randomized design and the main effects were set up in a factorial arrangement. The main effects within Houses 4 and 5 were strain and density. Following are general descriptions of the main effects:

Strain

The samples of fertile eggs from commercial breeder flocks were provided directly by the breeders involved. All eggs were set and hatched concurrently. A total of eleven white egg strains, 7 brown egg strains, and 1 heritage strain participated in the test. See the 38th Hatch Report (Vol. 38, No. 1) for details.

Density

In Houses 4 and 5, all individual replicateswithin each block contained one strain of layers. The cage density in both houses was dictated by the cage size that was either 61 or 81 cm wide and 41 cm deep. This allowed for two density combinations of 73 in2 (471 cm2) at 7 hens/cage (81 x 41 cm) and 77 in2 (497 cm2) at 5 hens/cage (61x 41 cm).

Layer Management (Molting):

The molt was conducted utilizing all hens involved in the layer test except for rows 1 and 2 in both Houses 4 and 5. Full Fed Control (NM) replicates were assigned rows 1 and 2 and were maintained according to the standard management program as outlined previously. The laying house will be partitioned such that the lighting program will be consistent for maximum egg production.

Non-anorexic Molt Program (NA) hens were fed a low protein, low energy diet with supplemental Ca for maintenance. It was designed to keep hens out of production and provide balanced nutrition for body maintenance only. The diet is bulky, such that a full trailer load will only weigh 2/3 of a normal full load. The birds in the replicates being molted were weighed every other day until target weight was reached then that replicate and sister replicates were returned to the resting diet until the end of the molting period. The induced molt was started at 69 wks of age.

The research project was to develop a standard weight loss curve which can be utilized by the egg industry in managing a non-anorexic molt program. Body weights were taken every other day. On 2 selected strains body weights were taken daily.

Procedural steps: Day -7 Sample of birds will be weighed to determine the pre-molt weight. Target weight loss (25 % body

weight) will be calculated using the pre-molt weight. Day 0 NA program instigated with the remaining layer feed being removed and replaced with the NA

molt diet and daylight hours reduced. Controlled light housing, reduce the day length to 9 hr. Remove morbid birds before feed restriction.

Day +28 Body weights were taken then the birds were fed layer diet and light stimulated. Specific monitored criteria for all of the molt programs include the following:

The birds to attain approximately 25% body weight loss. Maintain house temperature at 80+ 5o F, but the birds should not pant. House temperature management reacted to ambient environmental temperatures and weight loss rates.

6

The 1st post-molt production period light schedule is the guide by which the lights will be adjusted following the molt. Actual house conditions and the flock’s reaction to the NCSU Non-Fasting Molting Program may affect how the light stimulation will actually be given. In general the hens ceased egg production by Day 6-10 of the molt program. However, some of the Brown egg strains never achieved 0 egg production. The hens were allowed to consume all of the molt feed provided between feedings. The molting ration is designed to keep hens out of production and to provide for skeletal and muscle maintenance. Livability was excellent with this program.

Layer Nutrition:

Layer diets are identified as Diets D, E, F, G, H, I, M, N, and O which consist of a pre-lay diet and a series of layer diets formulated to assure a daily protein, mineral and amino acid intake as shown below. Feed was offered ad libitum in accordance with the guidelines that all birds should receive acceptable nutrient intake at all times depending on the bird’s age and production rate as shown in the Laying House Feeding Program Table.

The diets provided during the molt, consisted of a low protein/energy diet and a Resting Diet described in the Molt Diets Table which follow. The molt diets were formulated to provide nutrition for body maintenance. The Resting Diet provides layer with the nutrients needed to maintain a static body weight with no egg production.

1 If the egg production is higher than predicted values protein intake should be increased by 1% Note: House temperatures dictate the body maintenance demand of the hen if the house temperature is 75 to 80°F feed protein content should be increased accordingly to compensate for metabolic heat needed to maintain a homeostatic body temperature. If the house temperature is at or above 85°F no adjustment is needed.

Data Collection Schedule and Procedures:

Age at 50% Production (Maturity) - The first day at which the birds in the individual replicates achieved 50% production. Egg Production - All eggs that had the potential of being marketed were credited toward the test unit's (replicate) egg production, regardless of the shell condition at the time of collection. All eggs were collected and recorded daily. Egg production was summarized at twenty-eight day intervals, and was calculated and reported on a Hen-Housed and Hen-Day basis. Egg Weight--At twenty-eight day intervals, all eggs produced in the previous 24-hour period were weighed and sorted by size (See egg size distribution). Percentages of eggs within each size category, average egg weight (g), and egg mass (g) were calculated and reported. Egg Quality--At twenty-eight day intervals, all eggs produced within the previous 24 hours were examined by candling light and graded according to current USDA standards for egg quality. Eggs were graded in the pilot processing facility and handled as they would be in a commercial off-line facility. Egg Size Distribution--At twenty-eight day intervals, all eggs produced within the previous 24 hours were weighed and sorted according to current USDA standards for egg size. Egg Income--Egg income was calculated using current year regional average prices for farm value of eggs based on egg production and quality evaluation. Feed Consumption and Conversion--All feed offered for consumption was recorded for each replicate. At twenty-eight day intervals, feed not consumed was weighed back and feed consumption was calculated. Daily feed intake (kg/100 hens/day) was calculated and reported for each strain. Feed Costs--Feed costs were based on the actual current feed prices for each feed delivery which were calculated and summarized for the complete production cycle. Body weights—Birds were weighed and weights recorded at housing (17 wk), end of 1st cycle (69 wks), start of the 2nd cycle (73 wk), and at the end of the 2nd cycle (110 wk) . Body weight gain for the 1st cycle was calculated and reported for each strain. In the Molt period lowest body weight, percent weight loss, 73 wk body weights were taken or calculated and reported for each strain. Mortality--All mortalities were recorded daily, and obvious accidents or hens used for experiment sampling were not included in reported mortalities.

Statistical Analyses and Separation of Means:

All data were subjected to ANOVA utilizing the GLM procedure of SAS, with main effects of strain and density. Separate analyses were conducted for white and brown egg strains. Significant differences (P < 0.01) within white and brown egg strains are noted by differing letters among columns of means. The layer houses were not significant; therefore, data for houses 4 and 5 were pooled in this analysis. First and second order interactions were tested for significance. The LS Means from the GLM Procedure were separated via the PDIFF option.

DESCRIPTION OF DATA TABLE STATISTICS

Egg Size Distribution:

Following are the size classifications used for establishing the USDA egg size grading. There has been blending of egg size in this test with the weight cut off between medium and large being 23.5. This maximizes the number of USDA large eggs just as would occur in a commercial plant. The proportion of the eggs falling into the following size categories are reported in the tables. Table 12. USDA Egg Weights Used To Establish The Egg Size Distribution Weighted for Large Eggs.

Size Category Ounces/Dozen

Pee Wee < 18

Small 18 – 21

Medium 21 - 23.5

Large 23.5 – 27

Extra Large > 27 Feed Cost: The calculated feed cost per hen housed at 119 days, using the pounds/diet consumed and the average price of each diet per ton. Table 13. The Average Contract Feed Price For Feed Purchases During The First Cycle.
